Abstract
An electronic auscultation aid improves the performance and convenience of auscultation. The auscultation aid may include means for emphasizing sounds that may be associated with pathological or pre-pathological conditions. The auscultation aid may include a wireless interface for distributing a detected signal to one or more remote devices. The auscultation aid may comprise a mount for temporary attachment to a conventional acoustic stethoscope. The auscultation aid may include an apparatus for switching between active and sleep modes for the conservation of battery life.

33. An auscultation device, comprising;
-
a microphone, an amplifier for amplifying signals from said microphone, an emitter-detector pair for determining when said microphone is in a position to detect sounds from an auscultation subject, and a controller for powering down said amplifier when said emitter-detector pair indicate the auscultation device is not ready to detect sounds from said auscultation subject. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42)
